Gluteal implants

Sadri Ozan Sozer, Osman Erhan Eryilmaz
Postbariatric, cosmetic, and circumferential body lift patients seek to avoid a flattened buttock contour. Gluteal implants have been described with various rates of complications and difficulties. Lipografting moderately increases buttock volume; neither procedure directly addresses ptosis. The procedure described in this article addresses the volume deficit and ptosis. Most adipocutaneous flaps originate within the superior gluteal region and maintain volume in the top half of the buttocks, lacking the ability to reach the midportion of the buttocks...

Gluteal augmentation has gained popularity. It might be the only option to increase volume for lean patients without donor tissue for grafting. Subfascial augmentation is a safe treatment with low morbidity when performed in an appropriate setting with the right equipment. It is an anatomically based procedure. It is very important that pocket dissection is limited to the anatomic landmarks. Implants should be placed vertically to allow for proper contouring. The wound should never be closed with tension. One of the most important steps is postoperative care, which should avoid any pressure on the buttocks and stress on the wound...

Although interest in buttocks implant procedures is growing around the world, it remains a technically demanding procedure. The intramuscular plane is thought to be superior to other planes of dissection. Asymmetry and visibility of the implants remain frequent complications when the surgeon works without any reference points to guide the procedure. The XYZ method helps the surgeon to obtain symmetry, to significantly reduce implant visibility and to decrease other complications associated with buttocks implants...

This article presents an overview of intramuscular gluteal augmentation involving primary and secondary augmentation with implants. Although gluteal augmentation is a well-studied procedure, few reports have described the intramuscular technique or this technique in association with lipofilling. This article presents experience with a combined technique; this recent innovation combines placement of an anatomic silicone gel implant underneath the gluteus maximus and immediate fat grafting. Primary and secondary gluteal augmentations using implants resulted in satisfactory outcomes...

Submuscular gluteal augmentation is a very valid plane for buttocks implantation, even more so in North America, where surgeons can only use silicone elastomer implants. Irrespective of how soft elastomer implants are made, they are much firmer than the silicone gel implants that can be used in other countries. A deeper plane with more soft tissue coverage provides more natural results, as long as the anatomic boundaries are respected. Proper patient and implant selection is the key factor for satisfactory gluteal contours and outcomes...

Gluteal augmentation is rapidly gaining in popularity and this is driving aesthetic surgeons to gain experience and develop techniques to meet patient expectations. Currently, the 2 main techniques - gluteal fat grafting and gluteal implant for augmentation have significant limitations. Autologous fat grafting seems to have a mortality rate significantly higher than other aesthetic procedures. Implant based gluteal augmentation is equally difficult. This is a broad review of all the complications associated with both types and autologous gluteal augmentation...

Cosmetic procedures are common and utilize many techniques to obtain aesthetically good outcomes for patient satisfaction with acceptable safety standards. Cosmetic procedures that involve the gluteal region are becoming increasingly popular as various procedures can target the gluteal region such as liposuction, tumescent liposuction, cosmetic filler injections, autologous fat transfer, depot drug delivery, and implants. Complications of cosmetic gluteal procedures can be localized or systemic with systemic complications being responsible for most deaths...

BACKGROUND: Total hip arthroplasty (THA) is in most cases improving patients´ life quality immediately after surgery. However, a closer look at these patients, especially with modern gait analysis methods, reveals also negative consequences due to the surgical approach related injury to the pelvic muscles. We hypothesized that this damage will have a negative impact on hip joint contact forces during activities of daily living (ADL). METHODS: 10 patients undergoing THA received an instrumented hip joint implant enabling real time in vivo measurements of hip joint loads using a direct lateral approach...

PURPOSE: Occlusion of internal iliac arteries during endovascular treatment (EVAR) of abdominal aortic (AAA) and common iliac artery aneurysms might be associated with ischemic pelvic complications. This study evaluates technical and clinical success, safety and mid-term results of a novel iliac branch device (IBD) for revascularization of the internal iliac artery (IIA) during EVAR. MATERIALS AND METHODS: Retrospectively, we identified 21 men (mean age 73.3 ± 6...

Metal-on-metal (MoM) bearings in total hip arthroplasties and hip resurfacing arthroplasties have recently shown a new type of complication: adverse reactions to metal debris (ARMD). ARMD is characterized by local severe inflammation and tissue necrosis leading to implant failures. The gluteal muscle region is important for the patient outcome after revision surgery. This prospective positron emission tomography/computed tomography (PET/CT) study was undertaken to evaluate the characteristics of 2-deoxy-2-[18 F]fluoro-d-glucose ([18 F]FDG) and [68 Ga]Gallium citrate ([68 Ga]Citrate) PET/CT in ARMD patients...

A 30-year-old female presented with a three-month history of a multilocular cystic lesion over the lumbosacral spine. Fine-needle aspiration biopsy (FNA) of the lesion was performed at an outside institution, and a cytologic diagnosis, suspicious for chordoma, was rendered. The patient presented for surgical consultation at our institution. Repeat FNA demonstrated an unusual fat-like material. Upon further inquiry, the patient provided a recent history of gluteal contour improvement with fibroadipose tissue implants...

INTRODUCTION: Gluteal insufficiency is of concern with lateral approaches to total hip arthroplasty. Damage to the branches of the superior gluteal nerve may cause degeneration of the innervated muscles. The direct anterior approach exploits the intermuscular and internerval interval between tensor fasciae latae laterally and sartorius and rectus femoris muscle medially. In this study, the distance of the superior gluteal nerve in relation to anatomical landmarks was determined. MATERIALS AND METHODS: Two experienced surgeons implanted trial components in 15 alcohol glycerol fixed cadavers with 30 hips...

Soft-tissue augmentation and implants are increasingly seen by the radiologist as more techniques emerge for a variety of indications and locations. Some surgical and implant procedures are performed for purely cosmetic reasons in otherwise healthy patients seeking to improve their body image, and some are performed for reconstruction after cancer or other chronic illnesses. Abdominoplasty, liposuction, and autologous fat grafting can be performed for abdominal and gluteal contouring. Injection of liquid injectable silicone has historically been fraught with legal issues, although it continues to be used for augmentation in a variety of anatomic locations...

The aim of the present study was to evaluate the effect of different dosages of retarded vs. rapid release of bone morphogenic protein 2 (BMP2) at different recipient sites. Porous composite poly(D,L-lactic acid) (PDLLA)/CaCO3 scaffolds were loaded with three different dosages of rhBMP2 (24 µg, 48 µg and 96 µg) and implanted, together with blank controls, both into non-healing defects of the mandibles and into the gluteal muscles of 24 adult male Wistar rats. After 26 weeks, bone formation and expression of bone specific markers [alkaline phosphatase (AP) and Runx2] were evaluated by histomorphometry and immunohistochemistry...

The objective of this article is to examine dynamic changes of ischial blood perfusion during sacral nerve root stimulation against surface functional electrical stimulation (FES). Fourteen adults with suprasacral spinal cord injury (SCI) were recruited. The gluteal maximus was activated by surface FES or stimulating sacral nerve roots by functional magnetic stimulation (FMS) or a sacral anterior root stimulator implant (SARS). Ischial skin index of hemoglobin (IHB) and oxygenation (IOX) was measured.Skin blood perfusion was significantly higher during FMS than the baseline (IHB 1...
